HI,
The won hood is a complete package deal, it's shipped from the factory and they prepackage them in a wood crate, so would be difficult to get them to remove the bulb, but i'm sure they will do it, but iw ould recommend keeping the bulb because i doubt it would save you much to have it removed.
FYI, I just lowerd the prices on all the Won hoods today and they now also have 250watt.
We do carry XM lamps as well.
thanks
